Changes in SendMail

From Zarafa wiki

We are planning some changes in HandleSendMail and backend's SendMail. The main reason is that in ActiveSync protocol version 14 there are more properties we have to handle. Adding them to the SendMail's signature seems to not be a good idea because there's no guarantee there won't be any other new in the future. Instead of the current parameters there will be only one SyncSendMail object which will contain all necessary parameters.
